system calls *traditionally* returns 0 when successful and 1 when it fails.

system ( cmd ) && die "Error - could run cmdn";

# Retrieve the higher byte of the two-byte return code

my $ret = system("./server") >> 8;

$r = system("command .. e.g. search");
print"r is $rn";

Here, if $r is 0, that means command has executed successfully.
Any other value means command has failed.

Perl defines predefined variable $? which gives the return code of last command executed.
